COLORED GLASS-CERAMIC MATERIALS AND COLORED ARTICLES MADE OF SUCH GLASS-CERAMIC MATERIALS

摘要

Transparent &bgr;-quartz glass-ceramics containing vanadium oxide. Such glass-ceramics have advantageous optical properties including good transmission in the infrared range, low transmission in the visible range, and significant transmission in the blue range for thicknesses of 3 mm. They can be used as materials for cooking top plates.
